SAD-IRON.

Application fi led January is, 1910. Serial No. 538,591.

To all whom it may concern:

Be it known that 1, JAMES E. AUSTIN, a citizen of the United States, and a resident of Binghainton, in the county of Broome and State of New York, have invented a new and Improved Sad-Iron, of which the following is a full, clear, and exact description.

The invention relates to said irons heated by burning gas, such, for instance, as shown and described in the Letters Patent of the United States, No. 851,479, granted to me April 23, 1901. y

The object of the present invention is to provide certain new and useful improvements in sad irons, whereby the size of the mixing chamber for the gasiand air can be enlarged or reduced at the will of the operator, the burning gas is utilized to the best advantage and all danger by back firing is completely prevented and the usually unsightly chimney is dispensed with. For

. the purpose mentioned, the sad iron is provide'd with an adjustable mixing chamber, connected at the outer end with a gas su ply and opening at 1ts inner end nto the ho low body of the said iron.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification,

in which similar characters ofreference in dicate corresponding parts in all the views.

Figure 1 is a perspective view of the sad iron; Fig. 2 is a longitudinal central section of the same; Fig. 3 is a sectional plan view of the sameion the line 3-3 of Fig. 2;

' and Fig. 4c is a cross sectionof the same the bottom A and on the line 4-4 of Fig. 2. p

The body A, of the sad iron is shown as of the usual shape and made of two castings, one of which is hollow and comprises the sides A which converge and meet at the front of the body, and the other casting comprisesthe top A and the rear end A, the two castings being securely fastened together by screws B; On the upper surface of the top A rest the lugs C of a protecting plate 0, fastened in position by a bolt D, engaging the plate 0 and the top A as plainly indicated in the drawings. From the front and rear ends of the protecting plate C rise standards C connected with each other by a bolt E,-ca-r- Specification of Letters Patent.

Patented Apr. 28, 1914.

A of the hollow body are provided near the front end at the top with outlet openings A covered by a perforate plate G, fitted against the inner surface of the hollow body and resting at its lower edge on shoulders A, formed on the inner surface of the hollow body, the top ed e of the plate G being engaged by the un or surface of the top A, to securely hold the plate G in place without other fastening devices. The rear end A is provided with openings for the passage of air to the interior of the hollow body, and 011 the said end A is formed a boss A, in which is adjustably held a bushing H, by the use of a set screw 1, screwing in the boss A against the bushing H. The bushing H is inclined in a downward and forward direction, and its inner end is-covered by a perforate cap H, preferably in the form of a wire netting, to prevent back flashing of the burning. gas in the hollow body. On loosening the set screw I, the bu hing H can be moved in ward or outward in the boss A so as to bring the inner end of the said bushing nearer to or farther from a transverse lug A located on the upper surface of the bottom A, a distance from the rear end. or heel of the sad iron, as plainly indicated in Fig. 2. The bottom A, from the lug A to the front end thereof, is preferably pro- In the bushing H -'s mounted to slide a mixing chamber J, open at the front end and connected at its rear end with a pipe K, adapted to be connected by a rubber tube with a gas supply, and on the said pipe K is arranged an air admission valve L, for controlling the admission of air to thepipe K, to forni a mixture of air and gas to be burned in the hollow body of the sad iron. This valve L is preferably of the same detail construction as the one shown in the patent above referred to, so that further description of the same is not deemed necessary.

From the top A of the hollow body depends a lug A, to the under side of which is secured a deflector N, in the form of a plate, inclined downwardly and forwardly, and extending from the rear end A to the front endof the hollow body. The deflector N is provided at the sides with upturned flanges N, spaced from the sides A of the hollow body and extending to the under side of the top A. By this arrangement, the expansion chamber which extends between the bottom A and the deflector N is increased by the addition of the space formed between the flanges N and the sides A of the hollow body, as will be readily understood by reference to Fig. 4.

When it is desired to use the sad iron, the valve L is preferably closed and the gas turned on, so that the gas passes by way of the pipe K, the mixing chamber J and the perforate cap H into the combustion chamber of the hollow body, at which point the gas is ignited bya match or other lighting device, passed into the hollow body through the openings in the end plate A When the gas is burning, the valve L is opened, so as to permit air to enter the pipe K and mix with the gas, the mixture being very intimate, by the use of the mixing chamber d, which is larger than the pipe K, and can be enlarged in size or diminished by corre spondingly sliding the mixing chamber d outward or inward in the bushing H.

It is understood that when the gas is burning in the combustion chamber of the hollow body, suction is created in the mixing chamber J, and as the latter is larger than the pipe It; the entering air and gas are free to expand and thus become intimately mixed in the chamber J prior to passing through the perforate cap H into the chamber, to be burned therein.

It is understood that the transverse lug A serves to spread the flame in a transverse direction, so that the flame reaches all parts of the bottom A; and by having the deflector N inclined in a downward and forward direction, the flame is forced into contact with the bottom A throughout, the end thereof, prior to the products of combustion rising in the front end of the hollow body, to finally pass through the perforate plate G and the outlets A to the outer air. lit is further understood that the deflector N confines the most heat in the lower portion of the hollow body, thus evidently heating the bottom A desired to be heated, and at the same time the deflector N protects the top A against undue heat, to shield the operators hand having hold of the handles F. the hand being also protected from undue radiation of heat by the plate C spaced from the top A, to around the plate.

By the use of the perforate cap H, all danger of back flashing of the flame is prevented.

Having thus described claim as new and desire to Patent: p
